mycroft ca5dd9fee7 The AD1848/CS4231 attachment doesn't create DMA maps any more, so we have to
do it here.  This is preferrable anyway, since we're not actually doing DMA
through the AD/CS chip.

mycroft e5f5e628d2 Pass the direction to the allocm and round_buffersize methods.
Some drivers need this to properly allocate DMAable memory.

jtk 92707994ef use ad1848_isa_attach, so GUS cards with CS4231 don't panic the kernel 1998-09-01 18:48:38 +00:00
pk 2ffb54bdcc Split the AD1848 driver into MI (dev/ic/ad1848.c) and ISA parts. 1998-08-25 22:34:29 +00:00
augustss cd09067eb4 * Redo the way the way the MIDI driver attaches to audio devices.
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
  The opl driver is not finished yet; it sounds pretty awful.

For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.

augustss e7029fc0da Make the audio API (almost) SunOS compatible.
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.

augustss 25b465a80c Bus-ify the GUS driver. 1997-09-06 14:23:13 +00:00
augustss a50d4ba893 XXX Add a drq2 locator for the ISA bus. Many sound cards need
two DMA channels to do e.g. full-duplex.  This allows
a way of specifying the second channel in a sane way.
THIS IS TEMPORARY.  The drq2 locator will go away when
the locator system has been changed to allow multiple
values per locator.
1997-08-26 19:26:38 +00:00
augustss 6616d47838 - Change audio_hw_if a little: set_param now sets the play and record modes
at the same time instead by using two different calls.  This enables
  it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
  play and record settings are independent.
- Fix some buglets in audio.c.
1997-08-24 22:31:23 +00:00
augustss 332ad95e76 Change the MI audio driver so it attaches to the MD driver in the
normal way.  This requires adding a line to the config files to
get audio to work again.

augustss 658656bb99 Audio changes:
- Change the way attach and open works to allow multiple audio
	  devices.
	- Split the mulaw.c file into two to avoid dragging in mulaw
	  convertsion when they are not needed.  Add 16 bit alaw/mulaw tables.
	- Change the way audio properties are gotten.
	- Recognize more versions os SoundBlaster.

augustss a63034762b Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if.  Also remove a field from
audio_hw_if that was not read-only.

augustss d58bc6796f audio: Simplify handling of AUDIO_SETFD and committing of encoding mode. 1997-07-27 23:51:48 +00:00
augustss 9745684ebe Changes to the sudio system:
- It is now possible to handle devices that want "looping" DMA,
    e.g. the SoundBlaster correctly.  The WSS and SB drivers use this.
    To do this several new methods were introduced in audio_hw_if.
  - Different silence handling (forced by previous change).
  - The audio driver can now be mmap()-ed, but due to problems in
    the VM system only for writing for now.
  - The OSS (Linux) audio emulation takes advantage of some of the
    new features.

augustss 8727da130b In the name of backwards compatibility AUDIO_ENCODING_LINEAR has been
renamed AUDIO_ENCODING_SLINEAR and AUDIO_ENCODING_LINEAR reverts to the
NetBSD 1.2 sematics.  A kernel with COMPAT_12 defined will accept
AUDIO_ENCODING_LINEAR and treat it as before, without COMPAT_12 it
will be rejected.

jtk 877dcf7fc9 restore accidentally-lost set of nchannels in driver layer 1997-05-12 04:11:43 +00:00
jtk 9734adc67f use normal linear names/values for 8-bit encodings
mark mulaw as emulated (it's done via a mapping table)
use GUS query encoding routine, even on GUS max, since the encoding
stuff is handled by the GF1.
XXX might not be right for recording, but it's correct for playback.
1997-05-10 18:58:33 +00:00
augustss e63a553175 Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.
1997-05-09 22:16:27 +00:00
augustss c4a52794f1 Convert to new orthogonal audio encoding scheme and implement
some of the new encodings.  The change to ioctl AUDIO_GETENC is
NOT backwards compatible.
1997-05-07 18:51:31 +00:00
augustss 526ef2f618 Change the interface between the high and low level audio drivers
so that all audio encoding parameters are set at once.  This simplifies
the interface and make error checking easier.
